A-man, HS is trolling and you're rising to the bait. Never forget that he writes mostly to get a reaction. He is best ignored.
I believe Big-E's initial suggestion is correct - reduce DIN for younger children, as per the Salomon chart. Seven-year-old kids may be fast for their age, but they don't require compensation for large forces, impacts, etc. In fact, they may get into more trouble at slower speeds, where most of the damage occurs.
Some personal DIN (and Marker) experience:
1. Since these are only single data points their value, if any, is certainly limited.
2. I have had trouble with some Markers apparently pre-releasing upward at the toe, generally when the ski was strongly decambered in a trough between bumps. The release was effortless, the heel remained closed, and the ski remained traveling in the same direction. I was told that this might
be due to incorrect forward pressure adjustment. It might also be a software (pilot) error. After all, if I had been standing with pressure in front of my heel rather than behind it, my toe would have stayed down even if the toe wings opened for an instant.
3. I have a new pair of K2 system skis with Marker piston bindings. The rail mount allows the toe and heel to float around the point where the cam engages the ski, so the toe and heel are not forced together when the ski is strongly decambered. I have not had any prerelease problems, but I have not skied any icy bumps, either. The ski does
bend nicely when laid over on edge, and seems happy to carve an arc much smaller than its nominal sidecut radius.
4. I have skied Salomon bindings for years without prerelease issues, despite certain people telling me I should set the DIN higher to ski bumps. I do, however, carry a screwdriver to readjust the wings on the toepiece when they get loose. This is not an issue with most of this year's Salomon designs.
5. I did hyperextend the ligaments in the back of one knee once when I drove a ski tip into an unseen object at relatively low speed. The binding did not release. I subsequently reduced the DIN on the heel by 0.5 without introducing any prerelease problems.
I have had numerous releases. With the exception of the Marker releases mentioned above in item 2, they were all "honest" releases. For a few of them, I felt the forces were low, and I might have preferred it if the ski stayed on, but it least I was able to find the ski, put it back on, and ski out easily, even in those cases where I ended up well below my ski. In the case of #5 above, skiing out was very painful.
Sooooo...even though HS will think I'm gay (and so what if he does??), I prefer lower DIN settings most of the time. If I'm having trouble coming out too often, I take it as a sign that my technique needs work.
FWIW, I don't race, but I ski bumps, trees, powder, crud and steeps reasonably well, according to trained observers who should know.
